From ae98a0089ff7f7641ed15ddd595797de56eb49f1 Mon Sep 17 00:00:00 2001 From: Stephan Beyer Date: Fri, 16 Jan 2009 20:09:59 +0100 Subject: Move run_hook() from builtin-commit.c into run-command.c (libgit) A function that runs a hook is used in several Git commands. builtin-commit.c has the one that is most general for cases without piping. The one in builtin-gc.c prints some useful warnings. This patch moves a merged version of these variants into libgit and lets the other builtins use this libified run_hook(). The run_hook() function used in receive-pack.c feeds the standard input of the pre-receive or post-receive hooks. This function is renamed to run_receive_hook() because the libified run_hook() cannot handle this.
